JOSEPH W. C. SHIPMAN, OF LOS ANGELES, CALIFORNIA.

APRON FOR PHOTOGRAPHIC DEVELOPING EQUIPMENT.

Application filed .Tune 17,

To all whom it may concern:

Be it known that I, JOSEPH W. C. SH P- MAN, a subject of the King ofGreat Britain. residing at Los Angeles, in the county of Los Angeles,State of California, have invented a new and useful Apron forPhotographic Developing Equipment, of which the following is aspecification.

My apparatus relates to the art of photography, and more particularly tothe art of developing and fixing the photographic image. In this art itis common practice to produce an image on a sensitized film or paper,this film or paper then being subjected to the action of suitabledeveloping, fixing and washing solutions for the purpose of fixing theimage previously produced.

The object of my invention is to provide an apron by which such film,paper, or the like, hereinafter referred to as photographic material,may be rapidly and efficiently handled for the purpose of so developingand fixing the image.

Further objects and advantages will be set forth in detail hereinafter.

Referring to the drawings, which are for illustrative purposes only:

Fig. lis a plan view of the spacing apron. Fig. 2 is an edge View ofsame.

Fig. 3 is an edge view showing relationship between the photographicmaterial and the drying apron.

In the drawing I show a portion of photographic material which may beeither a length of film or sensitized paper. In subj ecting suchphotographic material to development processes, it is essential that theseparate layers or thicknesses of the paper, when rolled upon a drum,shall be kept spaced apart so that free access of liquids may beprovided thereto. The apron 40 provides a series of blocks 41 which arearcuated in form and which are connected together in pairs by laterallyextending bars 42, the bars with blocks attached to the ends thereofbeing linked together in consecutive arrangement by link members 43which flexibly engage loops 44 extending from the ends of the blocks 41.

In Fig. 3 of the drawing I show the man- 1919. Serial No. 305,698.

ner in which a sheet of absorbent material 45 may be wound upon theapron 40 with the photographic material 30, in order to facilitate thedrying thereof. The blocks 40 being of arcuated form, as shown, may bewound spirally into a roll and are of sufficient thickness to hold thebars 42 spaced apart so that the consecutive layers of material woundupon the bars will not come into engagement, and further provide spacesinto which development solutions may enter and come in contact with thesurfaces of the photographic material 30.

I claim as my invention:

1. In an apron for separating the successive turns of a roll ofphotographic material upon a reel, comprising: axially disposed rods ofproper length to accommodate the width of said photographic material tobe wound thereupon; blocks of proper thickness to separate said turnsmounted upon the ends of said rods; and hinged links connecting saidblocks at right angles to said rods.

2. In an apron for separating the successive turns of a roll ofphotographic material upon a reel, comprising: axially disposed rods ofproper length to accommodate the width of said photographic material tobe wound thereupon; blocks of proper thickness to separate said turnsmounted upon the ends of said rods, said blocks being arcuated toconform to the spiral which they assume when wound between said turns ofphotographic material; and hinged links connecting said blocks at rightangles to said rods.

3. In an apron for separating the successive turns of a roll ofphotographic material upon a reel, comprising: axially disposed rods ofproper length to accommodate the width of said photographic material tobe wound thereupon; blocks of proper thickness to separate said turns,mounted upon the ends of said rods; loops oppositely extending from saidblocks; and links connecting between said loops so as to form a chainstructure therewith.

4. In an apron for separating the successive turns of a roll ofphotographic material upon a reel, comprising: axially disposed rods ofproper length to accommodate the 100 Width of said photographic materialto be Wound thereupon; blocks of proper thickness to separate said turnsmounted upon the ends of said rods, said blocks being arc- 6 uated toconform to the spiral which they assume when Wound between said turns ofphotographic material; loops oppositely extending from said blocks; andlinks connecting between said loops so as to form a chain structuretherewith.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 10th day of June, 1919.

JOSEPH W'. G. SHIPMAN.
